PORATION OF NEW JERSEY l Application filed-January5, 1926,Sefia1'N6; 79,457, and in ere-at Britain January 13,192;

- This invention relates to machines for op erating upon shoe parts and is illustrated herein as embodied ina machinearranged to perform the heel-seat fitting operation upon,

solespriortotheir attachment to shoes.

Inthe manufacture 0t shoes to which Wood tachedit isusual to fit the heel-seat portions of the soles of the shoes for thereceptionof the concave or cupped attaching surfaces with which such heelsar'e provided by trim-- ming surplus stool; from theperipheralpom tions of the heel-seats of the soles. This preferably done by a out inclined relatively to the surface'oi the heel-seat so that the periphery of the heel-seat is beveled in c'o'n formity to the concave attaching face of the heel, themateri 211 thus removed having an ap- V proximately horseshoe-shaped form; The,

stock at the forward extremities of the-bevel is cut to produce a pair ofheelebreast engagprovide a simple, inexpensiveand' reliable machine for performing this heel-*seat' fitting operation.- With this object in View the illiis trated machine ,is provided vvilth'means for deforming. the heel-seatoi'asole so that a knife moved longitudinally troml' the rear" may cut the peripheral portion from a heeh seat, beveling the edge ofthe heel-seat leaving the chip thus termed attached to; the sole approximately at the he'e'l-breast liner The machine is alsoprovidedvvithmeans by which the Work is then repositioned so that,

by further movement of the knife, thechip: particularly wjperfbrmyrth, hegLsiefi g may be severed from the sole.

A. ieature of the invention. comprises work positioning: means arranged to' be straddled by the workso that oneportioii of the work:

may be operated upon While another'portion is guarded from the operating means. i, In accordance: with this feature, the llustrated heelesea't fitting machine is providedi'witha bar arranged to receive the work with the" heeLseat portion ot the-sole to be operated mately at the heel-breast'li'ne on theother sideof the-bar, in combination with-a knife operable to sever thechip from thesole while the heel-seat ortion of thesole is thusgtjiardedby the bar In accordance Witha further feature of the invention, the formatand some other kinds-ofheels are to he at--* tion ofthi's bar and its relation to the path of movement of the knifeare: such that the severing of the chip results in thefo-rmation of a pair of tabs having beveled ends adapted to overlie thenoverhanging breast of :1; Louis heel-,- torming an abutment againstwhich the heel may be positioned when itiis beinglocated for at-tachmentto the shoe andreinforeing' the attachment of the heel to the shoe; It

should be noted,v moreover that the formaltion of the bevelcut peripherallyofthe heelseat prior to the-severingo iithechip I the inner edges ofthese tabs also-tote eled sothat when the tabs are pressed-into engagement with the breast of a Louishee1, -they' merge intoits surface in such a way' that afterthe' breast of the heel is covered with the usual flap, they inno way injure its'ap p'earance. If the soles to be 'op'eratediipon' are for shoes having'heels of sucha no that tabs ofthis formation 'arewnot des for. example if the shoes are tohave Gtihah heels, by-an appropriate changeinthe for mat-ion of the bar straddledhythe heel seat' portion of the sole and the chip, thee may be severed exactlyat the heel-breast line-at right angles to thesurfaceof the sole,- or, within reaso ahlelimits, at a other desired position and angle. p

While thegillustrated machine isad'ap-ted' operation upon soles prior to their attachment to shoes,- it should be noted thatthe invention is not limited to a machine for per- Fig. 1 is a plan view of a preferred machine embodying the presentinvention;

Fig. 5 is a side elevation ofthe rear portion of a sole after it has been operatedupon as illustratedin Figs. 3 and 4; and

Fig. 6 is a plan view of the sole of Fig. 5 viewed from its attaching surface.

The illustrated machine is provided with a frame 10 having in its upper horizontal face a guideway 12 extending from frontto rear of the machine. Mounted in the guideway 12 is a slide 14 having pivotally connected to it one end of a link 16 which is pivotally connected at its other end to a hand lever 18 pivoted at 20 on the frame 10 by whichlever the slide 14 may be moved forwardly-and rearwardly in theguideway 12. "The'zslide 14 has fixed to it a splitting or trimming knife 22 having a cutting edge extending across the machine. The knife edge as'it travels forward and backward moves overand in light contact with the upper face of a plate 24 fixed to the frame 10" below the guideway 12. The plate 24 has formed in it a suitably shaped opening 26 (Fig.1) through which thejcentre portion of the'heel end of the sole is thrust by a die 28 which has a conraised position.

vex" upper face and which is carried on the upper end of a plunger 30 slidingly mounted in theframe and moved upwardly to thrust.

thecentral part of the heel p ortion throu'gh the opening 26 in the plate 24 by a treadleoperated lever 32 pivoted at 34 on the frame. The plunger 30 is returned by its own weight and its upward movement is limited'by an adjustable screw 36 mounted in the frame and in, position to be engaged by the lever 32.,

Theplate 24 is beveled on its under side to provide a thin margin round theedge of the opening 26, as shownat '38, and the beveled face at the sides of the opening has formed on it serrations or teeth 40 to hold the sole against lengthwise movement during the cutting operation. The plate24 may be adjusted forwardly or rearwardly to bring theopening 26 into proper relationto thedie 28, screw the heel endof the sole when it is presented beneath the plate 24 and over the die 28.

In the operation of forming the horseshoeshaped margin a sole 50 (Fig. 3) which may have previously had formed on it a flap 52 (which in the finished shoe extends over the breast face'of a Louis heel)is positioned in V the machine over the die 28 with its heel and against the gage 48. The die 28 is then raised,

as far as is permitted by the adjustable stop screw 36, to engage that face of the sole on which the breast flap 52 is formed and to bulge the opposite face of the sole through the opening 26 in the plate 24. The stop of the sole which is bulged through the plate, I cutting right through .to but not into the breast flap 52. The knife 22 is then moved back out of the. way and the sole removed from the machine. The edges of the portions thus parted are, owing tothe bulging, beveled as shown at 54. The distance along'the sole to which the split is carried is determined by the adjustable stop screw '44 on the frame which engages the projection 46. This splitting action forms on the sole a flap 56 (Figs.

3 to 6) connected at its inner end to the sole, which has formed on it the convex or'bevelmargin surface 54 to receive theconcave heelseat'surfaceof the heel and this flap is surrounded by a horseshoe-shaped chip or trim-' ming of material 58 which is still connected at its opposite ends (at each side of the flap 56 at the termination of the cut) to the sole approximately at the heel-breast line. This strip'58 is later severed from the sole by the knife 22. For thispurpose strip 58 is inserted between a bar 60 and the knife 22, in

I the position-shown in Fig. 4, with the heelbreast flap 52 turned up out of the path of the knife 22 and the heel-seat flap 56 extendlng down in front of the machine and in front of a gage'bar 62 which functions to guard the flap'56 during the chip severing operation andwhich is adjustably secured to the frame of. the machine by screw and'slot connections 64. Gage bar 62 extends into the anglebetween the portion 58 to'be cut off and the convex heel-seatflap.portion 56, the work thus straddling-bars 60 and 62. The portion 58 to be cut off is thrust down as far as is permitted by the gage bar 62so that the posi tion of this gage determines the positionalong the sole at which'the cuts are made. Gage bar 62 also guards the heel seat portion of the sole from injury by theknife22 as the portion 58' is cut ofi, The angle of the cuts,

shown at 63, is determined by the angle of the upper face of the bar 60 against which the'horseshoe-shaped trimming is pressed by the knife 22, bar 60 thus co-operating with of said stations and to severthe chip thus formed from the heel seat portion of a sole two thus forming a pairof shear members.

The upper surfaceof bar is serrated to prevent movement of the trimming by the knife '22. The cuts, through the horseshoe ends extend forwardly of thesole from the tread face, that is the face adjacent to the breast flap, toward the attaching face. The

die 28 is at this time in its lowered position and the stop 46 is therefore out of the path of the stop-screw 44 so that the slideor carrier 14 can be moved further forward, beyond the 'positiondetermined by the stop 46 and screw 44, to cause the knife 22 to make the severing cuts. The extentofthis lattermovee ment is limited by the-engagement ofa pertion of the slide 14 with the-frame or by any other suitable arrangement.

vil/Vhen the material is removed inthe manner just described, short beveled projections or tabs 66 remain extending towardsthe heel end of the sole alongsidefthe convex heelseat flap 56 at opposite sides of the sole. These tabs 66 are well adapted to buttress and position a Louis heel longitudinally, in part by the junction of the heel-breast and heel-seat of-the heelseating itself against the junctions of the projections and the heelseat of the sole where the first knife cut terminates and in part by the contact of the projections themselves against the heelbreast, it being understood that in the finished shoe the projections extend up' the breast. face of the heel and'lie on it beneath the breast flap. Sincethe tabs 66 are beveled transversely, they may if necessary, be

moved in or out alittle to causetheiriouter' edges to line up with the breast corners the heel. Als0 their beveled ends cause them n to merge unnoticed into thebreast surface of the heel. V 7
